1 SECURED CLOSURE SYSTEM FOR SWING SHUTTERS Field of

  The invention relates to a secure closure system for flaps in which a cross bar is pivotally attached to one of the leaves of the flaps to take either a vertical position of opening flaps, or a horizontal position secure closure of shutters. The invention finds applications in the field of secure closure, with shutters, windows and doors for residential premises or commercial premises. State of the art At present, it is important to ensure a secure closure of the premises, for commercial or residential purposes, in order to prevent any break-in by burglars. The secure closure of these premises concerns mainly the openings of these premises, that is to say windows, doors and French windows. To prevent break-ins of burglars, it is conventional to install shutters outside windows and other doors and close these shutters by means of a secure closure system.

  Currently, there are different types of shutters, such as shutters and shutters. The flaps are flaps comprising two panels, called vents or flaps, each mounted on hinges fixed on either side of the opening of the window. When the shutters are closed, the leaves are placed side by side and fixed with each other by means of, for example, a cremone. A espagnolette, also called espagnolette, is a turntable fitting having a rod fixed on one of the leaves and a hook fixed on the other leaf and receiving said rod. Two leaves fixed together by means of a cremone can be easily fractured by a burglar who would insert a crowbar between the two leaves and pull, by means of the crowbar, on one of the leaves for break it up. Such a cremone closure system is relatively weak because, in particular, it has only one point of attachment of the two leaves.

2909120 2 To secure this fastening system cremone, it is known to use security bars. The safety bars are longitudinal rods made of a particularly strong metallic material, such as cast iron, and placed on U-shaped supports, themselves fixed on each of the leaves. The safety bar has the effect of keeping the two leaves side by side and stiffening each of the leaves. A burglar inserting a crowbar between the leaves will not be able to separate the leaves. However, such a security bar is particularly heavy. In addition, such a safety bar must be placed per user in the U-shaped supports, at the risk of jamming a finger between the bar and said U-shaped support. Moreover, this bar being a part independent of the shutter, the users are used to storing these safety bars at a place sometimes distant from the shutters. Thus, when the user wishes to secure the closure of his room 15 by means of such a bar, he must carry this bar relatively heavy from his place of storage to the shutters and then place this bar on the U-shaped supports, with the risks explained previously. Then, when the user wants to remove this security, he must lift the bar, carry it and store it in his usual place of storage.

Because of the weight of such a security bar, the difficulty in setting it up and removing it is relatively restrictive, in particular for the elderly and the disabled, with the result that most users do not secure. not regularly closing their shutters. They tend to secure their shutters only for long absences, whereas burglars often operate for a short time. In addition, for greater security, it is known to use several security bars simultaneously (two bars, or even three pairs of leaves) distributed over the height of the flaps, which multiplies by 30 as much the difficulty of setting place and removal of the safety bars. DISCLOSURE OF THE INVENTION The object of the invention is precisely to remedy the disadvantages of the techniques described above. For this, the invention proposes a secure closure system comprising a crossbar, mounted on one of the leaves of the flaps movably so as to take a vertical position 2909120 in which the flaps are free, that is to say they can be opened, and a horizontal position in which the shutters are closed and secured.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION The invention relates to a secure closure system for flaps. In the invention, the term "flap shutters" means flaps comprising one or more panels, called flaps or leaves, of wood, PVC or any other material that can be used for the manufacture of flaps, capable of being placed side by side ( when they are at least two) and to be locked in the frame of an opening made in a room, for example, a window, a door or a French window, single or double, to ensure shutter. The invention will be described in the case where the flaps have two flaps to lock against each other, in a window frame. It is understood that the invention can also be applied to shutters comprising a single flap to be locked in a window or door frame or to flaps having three or more flaps to block against each other.

The closure system of the invention comprises a cross bar mounted to be movable about a point of rotation in order to successively take a first position, namely a vertical position, and a second position, namely a position horizontal. In its vertical position, the crossbar is placed along the height of the leaves, parallel to the joint between the two leaves. In this position, the leaves of the flaps are free, that is to say they are not blocked and they can be opened by the user. In its horizontal position, the crossbar is placed along the width of the leaves, perpendicular to the join of the two leaves. In this position, the 5 shutters are secured, that is to say that they are closed and blocked in particular by the crossbar. In Figures 1A, 1B and 1C, there is shown an example of double-leaf shutters equipped with the closure system of the invention. These shutters 1 are mounted in a window frame 2. The closure system 10 of the invention comprises elements 3, 4, 5, 6, 8, 9 fixed on the shutters 1 and elements 7 fixed on the frame of window. Figure 1A shows the closure system when the flaps 1 are free. In this case, the cross bar 3 is in the vertical position. The cross bar 3 is mounted movably on one of the flaps of the flaps.

In the case of FIG. 1A, the crossbar 3 is mounted on the left flap 1b by means of a pivoting device 4. The cross bar 3 is held in this vertical position by means of a retaining tab 8, placed on the same flap as the cross bar, near the bottom end 3b of the crossbar. This retaining tab 8 serves to prevent the bar 3 from pivoting beyond a predefined position, namely the vertical position. This retaining tab 8 is placed at the bottom of the left flap 1b with an opening directed towards the right flap 1a to receive the cross bar when the latter passes from its horizontal position to its vertical position. Thus, when the bar 3 is in a vertical position, it is housed in the opening of the retaining tab 8. In FIG. 1B, the cross bar is shown when it is in the intermediate position, it is that is, when it has been pushed by the user so that it leaves the retaining tab 8 and that it is moving towards its horizontal position.

In FIG. 1C, the cross bar 3 is shown in a horizontal position, that is to say in a position for securely closing the shutters. In this position, the crossbar 3 is held by means of holding elements and, in particular, two blind latches 7a and 7b which prevent the cross bar 3 from continuing its rotational movement 35 beyond the horizontal position. The crossbar 3 is also held in this horizontal position by means of a holding lug 6. A pivoting hook 5, which will be described in more detail later, at least partially surrounds the cross bar and thus prevents said bar 3 to move out of its horizontal position to return to an intermediate position or a vertical position until the user has done the necessary to release the bar 3. As previously explained, the cross bar 3 is held by blind locks 7a and 7b. Examples of these strikes are shown in Figures 2A and 2B. These strikes are pieces of metal or plastic fixed on the window frame 2, that is to say on the walls 2a and 2b located on either side of the shutters. Each of these dead bolts has a U-shaped section. More specifically, each blind strike has a base 70 surmounted by an element 71 in the shape of a U or an inverted U. The base 70 is fixed on the wall. It can be fixed by means of screws 72. In this case, the base comprises orifices ensuring the passage of the fixing screws. Such a deadlock can be made in one piece, for example by molding, or from two separate parts (the base and the U-shaped element) welded to one another. In the example of FIG. 2A, the blind keeper 7b is directed towards the top, that is to say that the opening of the U-shaped part intended to receive the cross bar 3 is directed towards the top of the shutters. . In this way, the blind keeper 7b can receive the bar 3 when it passes from its vertical position to its horizontal position. In the example of FIG. 2B, the blind keeper 7a is directed downwards, that is to say that the opening of the U-shaped part intended to receive the cross bar 3 is directed downwards from the shutters. . In this way, the blind keeper 7a can receive the bar 3 when it passes from its vertical position to its horizontal position. Thus, the blind keeper 7b of FIG. 2A is intended to be placed on the left wall of the window frame and the blind keeper 7a on the right wall of said window frame, in the case where the cross bar is mounted in way to rotate, from its vertical position to its horizontal position, in the opposite direction of clockwise. The two strikers 7a and 7b are thus fixed so as to be head-to-tail relative to one another, which has the effect of blocking the rotation of the crossbar during closure of the system. It is then understood that the latches 7a and 7b may be identical but fixed in an inverse manner with respect to each other. Thus, blind locks serve as a stop at the cross bar.

They also have the advantage over a single abutment of preventing access to the crossbar from outside the flaps. In other words, a burglar equipped with a crowbar can not reach the crossbar and lift it since the ends of said cross bar are hidden in the U-shaped parts of the dead bolts.

The system of the invention also comprises at least one pair of interlocking elements 9a, 9b mounted at the joint of the two wings. As shown in Figure 1A, a pair of interlocking elements 9a is mounted at the top of the flaps; another pair of interlocking elements 9b is mounted at the bottom of the shutters.

An example of a pair of interlocking elements is shown in FIG. 3. This pair of interlocking elements 9b comprises two elements 92, 95 each fixed on one of the flaps of the shutters. In the example of Figure 3, the element 92 is fixed on the right flap 1a and the element 95 on the left flap 1b. Each of these interlocking elements is substantially L-shaped, with a leg L 90, 94 vertical and a foot L 91, 93 horizontal. Each element is fixed on a flap of the flaps by means of, for example, a set of screws and nuts 96. The nuts on the outside of the flaps are preferably nuts with round heads to prevent any disassembly of these rooms, from the outside, by a burglar.

The two L-shaped elements 92, 95 are mounted head to tail with respect to each other. Thus, on one of the wings, the L-shaped element 95 is placed so as to form an L and on the other of the wings, the L-shaped element 92 is placed so as to form an inverted L. It is thus clear that, when the flaps are closed, the two elements 92, 95 partially overlap each other 30 each ensuring the blocking of the leaf on which it is not fixed. In other words, the elements 92, 95 ensure a respective blocking of the two wings 1a and 1b. Thus, a burglar using a crowbar inserted between the two flap flaps can pull the flaps outwardly because the pair of interlocking elements will have the effect of blocking the two flaps with each other.

Advantageously, to facilitate the overlap of the two elements in L when closing the shutters, said elements are non-planar. In other words, the foot of L 91, 93 forms with the leg of L 90, 94 a non-flat angle, between 0 and 45.

FIG. 3 also shows a retaining tab 8 fastened to one of the shutter flaps and intended to receive the crossbar 3 when it is in a vertical position. This retaining tab 8 has a substantially Z-shaped shape. This lug 8 comprises a bar 81 of the Z fixed on the flap 1b and a leg 82 of the Z which forms a notch for receiving the cross bar 3. This retaining tab 8 its role is to prevent the cross bar 3 to exceed its vertical position when the user moves from its horizontal position to its vertical position. Like the interlocking elements, the retaining tab is fixed on one of the flaps by means of wood screws or screws and nuts, with round head nuts placed on the outside of the flaps. It may also be the same for all elements and parts of the system of the invention fixed on the flaps of the flaps. FIG. 4 shows a U-shaped retaining lug 6 forming a stop for the cross bar 3. This retaining lug 6 comprises a base 62 fixed to the flap 1a, for example by means of a screw 63 , and a support 61 provided with an oval opening 64. This support 61 has substantially an inverted U-shape. The opening 64 is directed towards the bottom of the flaps and has a shape adapted to receive the crossbar 3. Thus, this holding lug 6 makes it possible to block the trajectory of the cross bar when it passes from its vertical position to its horizontal position. In Figures 5A and 5B, there is shown a pivot hook of the system of the invention. This pivot hook 5 is mounted on one of the flaps of the flaps, for example the right flap 1a, in the example of Figure 5B. This pivot hook 5 comprises a tab of the support 51 which may be identical to the tab 6 described above. This holding lug 51 is fixed on the flap 1 has flaps. The pivot hook 5 further comprises a circumferential element 52, pivoting, able to close the oval opening 54 of the holding lug 51. This circumferential element 52 has the shape substantially of a C. As shown in FIG. circumferential member 52 is parallel to the holding tab 51 and movable relative to the tab. For this, the circumferential element 52 is mounted so as to be able to rotate about a point of rotation 53 of the holding lug 51. This point of rotation 53 can be obtained for example by means of a rivet assembling the circumferential element 52 and holding lug 51 with a certain clearance. It will be understood, then, that circumferential element 52 can rotate freely (i.e. with little friction) around rotation point 53, parallel to the tab 51, so that, in a first position, it leaves free the opening 54 of the pivoting hook 5 and, in a second position, it closes the opening 54. The first position is an unstable position obtained when the cross bar 3 or the user pushes the circumferential element 52. The second position is a stable position in which the circumferential element 52 returns as soon as the cross bar is fully entered in the opening 64 or when the cross bar is away from the swivel hook 5.

Figure 5A shows the pivot hook 5 when the bar is moved away from said hook. Figure 5B shows the pivot hook 5 in the case where the cross bar 3 is inserted into said hook. It can be seen that the crossbar 3 is placed in the opening 64 of the holding lug 51 and that the circumferential element 52 partially surrounds said crossbar. The crossbar is thus surrounded, on the one hand, by the holding lug 51 and, on the other hand, by the circumferential element 52. In particular, the circumferential element 52 surrounds the bar 3 in the open zone of the holding lug 51, which ensures a retention of said cross bar to prevent it from leaving its horizontal position.

When the user wants to open the flaps, he must actuate the circumferential element 52 by raising it up flaps to clear the cross bar 3 which can then pivot to its vertical position. This pivot hook 5 has the advantage of being easy to handle because a slight pressure on the circumferential element 52 is sufficient to lift it to allow the user to push the cross bar 3 downwards. In addition, when closing the system, the cross bar 3, arriving at the proximity of the pivot hook 5, pushes the circumferential element 52 upwards. The circumferential element 52 pivots so that the crossbar can be introduced into the opening 54 of the holding lug 51. As soon as the bar 3 is in the opening 54 of the holding lug 51, the element circumferential 52, due to its unstable position, falls back into its stable position, surrounding the crossbar. In the case of double leaf flaps, the holding lug 6 and the pivoting hook 5 are advantageously mounted on the flap opposite to that on which the cross bar 3 is mounted. In the system of the invention as described above, it is explained that the cross bar 3 is pivotally mounted on one of the shutters flaps. For this, the crossbar is installed in a pivoting device 4, fixed on a flap of the flaps. This pivoting device is shown in Figures 6A and 6B. Figure 6A shows the pivoting device 4 when the crossbar 3 is in its vertical position. Figure 6B shows the pivoting device 4 when the cross bar 3 is in its horizontal position. This pivoting device 4 comprises a base 41 fixed on the flap 15 1 b flaps. This base 41 is fixed by means of screws and nuts with round head, as explained above. The pivoting device 4 further comprises a support 42 movable relative to the base 41. This support 42, also called slide, comprises a ring 42a in which is inserted the crossbar 3 and a rotary lug 42b fixed to the ring 42a and movable around a rotation point 43. The rotary lug 42b may comprise a first zone fixed on the ring 42a and a second zone, perpendicular to the first zone, fixed on the base 41 by means of a rivet or rivet. a screw / nut assembly with a certain clearance. This fixing with clearance constitutes the point of rotation 43. The slide 42 is thus free to rotate about the point of rotation 43. The crossbar 3 is installed in this slide 42 and fixed on said slide, for example, by means of set screws 44. It is therefore understood that the crossbar 3 is movable around the point of rotation 43. It will be understood, on reading the foregoing, that to close equipped shutters of the system closure of the invention, the user must pull towards him the two leaves 1a and 1b flaps so that said leaves are side by side, in the same plane; it then rotates the crossbar 3 counterclockwise until the bar is inserted into the holding lug 6 and the pivoting hooks 5. At this time, the end 3b of the cross bar 3 is inserted 2909120 12 into the blind keeper 7a and the end 3a of said bar 3 is inserted into the blind keeper 7b. The interlocking elements overlap each other. The bar 3 is then locked in the horizontal position. The closure system is therefore secure.

To open the flaps, the user must lift the circumferential element 52 of the pivot hook 5 to disengage the crossbar 3; it then rotates the bar 3 in the direction of clockwise until said bar 3 reaches the retaining tab 8. The user can then push the two leaves simultaneously to obtain their opening.

In one embodiment of the invention, the crossbar 3 is made in an elongate tube. The slide 42 of the pivoting device 4 can then be made in a conventional spanish flail body. In a preferred embodiment of the invention, the cross bar 3 is made so that its lower end 3b is heavier than its upper end 3a so that the pivoting of the bar, when it opens, is driven by the weight of said bar. In this way, the handling of the crossbar 3 is facilitated. The maintenance of the bar 3 in the vertical position is ensured, not only by the retaining tab 8 but also by the effect of gravity on said bar. It will be understood, moreover, that this difference in mass between the two ends of the crossbar has no effect on the horizontal positioning of said bar since the pivoting hook 5 maintains the bar.
